Families of Conformal Fixed Points of N=2 Chern-Simons-Matter Theories

, 2010
We argue that a large class of N=2 Chern-Simons-matter theories in three dimensions have a continuous family of exact IR fixed points described by suitable quartic superpotentials, based on holomorphy. The entire family exists in the perturbative regime.

Black Holes in (Quartic) Quasitopological Gravity

, 2012
We construct quartic quasitopological gravity, a theory of gravity containing terms quartic in the curvature that yields second order differential equations in the spherically symmetric case.

Intelligent Reflecting Surface-Assisted Dual-Function Radar-Communication System

IEEE Access, 2023
We consider the design of a Dual-Function Radar-Communication (DFRC) system, aided by an Intelligent Reflecting Surface (IRS). The radar precoding matrix and IRS parameters are optimized to maximize the weighted sum of the signal-to-noise ratio (SNR) at ...

Nonperturbative evaluation of the partition function for the real scalar quartic QFT on the Moyal plane at weak coupling

, 2018
The remarkable properties of the real scalar quartic quantum field theory on the Moyal plane in combination with its similarity to the Kontsevich model make the model's partition function an interesting object to study.

Classical Chaos in a Driven One-Dimensional Quartic Anharmonic Oscillator

Computation
In this work, we investigate the transition from regular dynamics to chaotic behavior in a one-dimensional quartic anharmonic classical oscillator driven by a time-dependent external square-wave force.

Mellin Transform of Logarithm and Quotient Function with Reducible Quartic Polynomial in Terms of the Lerch Function

Axioms, 2021
A class of definite integrals involving a quotient function with a reducible polynomial, logarithm and nested logarithm functions are derived with a possible connection to contact problems for a wedge.

Do the gravitational corrections to the beta functions of the quartic and Yukawa couplings have an intrinsic physical meaning?

Physics Letters B, 2017
We study the beta functions of the quartic and Yukawa couplings of General Relativity and Unimodular Gravity coupled to the λϕ4 and Yukawa theories with masses.

Design of High‐Energy Anode for All‐Solid‐State Lithium Batteries–A Model with Borohydride‐Based Electrolytes

Advanced Materials Interfaces, EarlyView.
This study proposes a function‐sharing anode design to enable nonmetallic lithium insertion while maintaining intimate interfacial contact with the solid‐state electrolyte. A combination of lithium‐compatible and conformable borohydrides, highly conformable indium metal, less‐graphitized acetylene black, and a layer of highly graphitized massive ...
